Registered / ECC (Buffered) Memory Modules

ECC - Short for Error-Correcting Code memory, a type of memory that includes special circuitry for testing the accuracy of data as it passes in and out of memory.

Registered Memory - A memory module that contains registers that hold the data for one clock cycle before it is moved on to the motherboard. This process increases the reliability of high-speed data access. Registered memory modules are typically used only in servers and other mission-critical systems where it is extremely important that the data is properly handled.
